ADJUSTABLE VISE-SUPPORT.

SPECIFICATION forming part of Letters Patent No. 599,087, dated February15, 1898. Application filed September 9, 1897. Serial No. 651,074,. (Nomodel.)

place in various positions while work is being performed upon it, butprincipally for holding pieces of furniture while being upholstered. Weattain these objects by the mechanism illustrated in the accompanyingdrawings, in which Figure 1 is a top view, part in section, on

the line 1 2, Fig. 3. Fig. 2 is a vertical section on the line 3 4, Fig.1, also a vertical section through the center of the arm on the line 56, Fig. 3, the arm shown partially broken away. Fig. 3 is a back VlBW ofthe upper part only.

Similarletters refer to like parts throughout the drawings. The stand Ais intended to be fastened rig idly to the floor. It is constructed toreceive the shaft B, which is adjustable vertically,

and is secured in any desired position by the set-screw a or otherdesirable fastening. The upper end of the shaft B is constructed toreceive the flanges O and D, the flange 0 being fast to the shaft B andthe angle of flange D fitting loosely, so as to revolve freely, the facein contact with the face of the flange C. The flange D should be held inposition by the nut b or other effective means. The face of flange E isheld in contact with the face of flange D by a stud and nut in likemanner and revolves against the face of the flange D in a verticaldirection.

The projection c on the flange E is constructed to receive the tubularshaft G, which it holds firmly, also so as to permit the rod H to passthrough and revolve freely. For our purpose a thread is cut on theprojecting end of the shaft G to receive the hand-wheel d, though a nutmay be used instead of the hand-wheel cl ora'cam used in place ofeither,

in which case no thread is necessary as for the hand-Wheel or nut.

The tube F passes freely over the outside of the tubular shaft G, andthe one end comes in frictional contact with the projection 0, againstwhich it is made to impinge by the action of the hand-wheel d or otherdevice for that purpose.

The'vise I, of whatever form used, is intended to be. fastened firmly tothe tube F, but in such manner as to be easily released and shiftedlengthwise of the tube at the pleasure of the operator.

The vise can be moved to any position radially with the shaft byreleasing the tube F by a movement of hand-wheel cl and revolving on theshaft G until the vise is in the desired position, and then securing thetube F by tightening the hand-Wheel, thus holding the tube F rigidly inany desired position by the friction on the ends. This arrangement oftubes, in combination with the rod H, we call the vise-arm, which can bemoved in a vertical direction to any desired position Within asemicircle by the rotation of the flange E. To hold it firmly in adesired position, there are notches e e e in the edge of the flange Dand a single notch f in the edge of the flange E. The end of the rod His bent at an angle in such a manner (see H, dotted lines, Fig. 3) as tofall in the notches e e e when they come opposite the notch f. Therod'after passing through the projection c and the shaft G is fittedwith a small hand-wheel g, by means of which it is rotated.

A spiral spring h is shown, one end of which is held by a disk 1', whichis fastened inside of the tube G. The other end is held by a smallcollar j, which is fastened to the rod H. The other end of the rod H,which drops in the notches-and which we call the dog, is lifted out ofthe notches by the rotation of the rod H by means of the hand-Wheel gand drops back by the reaction of the spring h.

By this construction a piece of Work which is held in a vise which issecured to the visearm can be placed in any position around the centralshaft A by the rotation of the flange D on the flange 0, so thatadvantage can be taken of light or for any other reason, and that alsowhile being held at any vertical angle by the rotation of the verticalflange E and the action of the dog H, while at the same time it can beplaced in any desired position radially with the arm by the rotatingmovement of the tube F.

We claim as our invention and desire to secure by Letters Patent- 1. Inan adjustable vise-support, a vertical shaft B'held by the stand A orits equivalent in such a way as to be adjust-able vertically, supportinga construction of which an arm for holding a vise forms a part, and bymeans of which construction the arm can be moved to any desired positionradially with the shaft B, either vertically or horizontally, and heldfirmly in such position, while at the same time the vise can be adjustedlengthwise or radially with the arm, independent of the other movementsas shown and described.

2. In an adjustable vise-support, a stand holding a vertical shaftB incombination with the flanges C, D, E, and the arm F, the arm adjustableradially, horizontally, by the action of the flange D, in connectionwith the flange O, and the shaft 13, and radially Vertically by theaction of the flange E in combination with the flange D and theoperation of the dog 11, substantially as shown and described.

3. In an adjustable vise-support, a stand A, and shaft B in combinationwith rotating flanges O, D, E, and the arm composed of the annular tubeG, secured in the flange E, and the outer annular tube F, the hand-wheeld for securing the tube F in position, the rod H extending through thetubular arm G, operating as a dog in the notches e, e, e, in the flangesD, E, in combination with the spring h, the disk 1', the collar j andthe hand-wheel g, all substantially as shown and described.

In witness whereof we have hereunto signed our names in the presence oftwo subscribing witnesses.

CORNELIUS o. WRIGHT. WILLIAM HUNT.
